I note the comments on that patch talk about from: sender at host  rather 
than sender at domain ... so, its possible it triggers on the host that the 
sender is using rather than the domain in the 'from' header.



ugh, i used to know what ...

R$+ <@ $+ >		$:$&f@$j<>$1<@$2>		prepend local sender
R$+@$+@$j<>$+<@$+>	$:$1@$2<>$3<@$4>		avoid duplicate domain
R$+@$+<>$+<@$+>		$:$(mailertable From:$1@$2 $:@$2 $)<>$3<@$4>
R$*@$+.$+<>$+<@$+>	$:$(mailertable From:$2.$3 $@$1 $:$1$2 at .$3 $)<>$4<@$5>
R$*@$+<>$+<@$+>		$:$(mailertable From:$2 $@$1 $: $)<>$3<@$4>
R$-:$+<>$+		$@$>MailerToTriple <$1 : $2> $3
R$*<>$+<$+>		$:$2 <$3>




would do, but I'll be damned if I remember how that .cf stuff works 
anymore   :rofl:
